Application led February 25, 1904. Serial No. 195,155.

To all whom it may concern:

lSe it known that I, Ganar J. DORMANDY, a citizen of the United States,residing in Troy, county of Rensselaer, and State of New York, haveinvented certain new and useful Improvements in Folding-h/Iachines, ofwhich the following is a specification.

My invention relate-s to machines for inturning or infolding the edgesof blanks for cuffs, collars, or like articles; and more particularly tomechanisms and parts for effecting the folding and pressing of the foldsof blanks to constitute the two parts of a cuff or analogous articlepreparatory to sewing such parts together.

One of the principal objects of my invention is to produce a machinethat will afford a more simple construction and operation and moreparticularly by employing a single member or part which shall fill theoflice of a die or templet for dening the folds of the blanks, and thefurther oflice of effecting a creasing` pressure upon the folds of theblanks.

Other objects will appear during the description hereinafter following:

I will first describe a folding machine embodying my invention and thenpoint out the novel features in claims.

In the accompanying drawings, Figure l is a top view of a foldingmachine embodying my invention, the particular machine illustratedtherein being one adapted for the infolding of cuff blanks having foursquare corners. Fig. 2 is a cross section taken upon the plane 2%2 ofFig. l. Fig. 3 is a cross section similar to Fig. 2, but showing theparts in dierent position or stage of operation. Fig. 4t shows a crosssection similar to Fig. 3 with the parts in a still different stage ofoperation. Fig. 5 is a top or plan view of the templet illustrated inFig. l and its operating mechanism, the same being indicated on anenlarged scale. Fig. 6 is a plan view similar to Fig. 5, but withcertain parts removed in order to show in detail the operating mechanismfor the templet plate. F 7 is a bottom view of the templet shown in Fig.Fig. 8 is a view similar to Fig. 7 but with portions of the templetplates removed in order to more clearly show the operating mechanismtherefor. Fig, 9 is an enlarged cross section of the templet of Fig.

1 3, with the parts shown in the same stage of operation as in said Fig.3. Fig. 10 is a detail view of the operating handle for the templetshown in the above described figures, and the means whereby its extentof throw is limited at the will of the operator. Fig. 1l is anotherdetail view on an enlarged scale of certain parts of the machineillustrated in Fig. 2 herein.

Similar letters of reference are employed to designate correspondingparts in the several figures of the drawings.

designates the bed of a folding machine embodying my invention, whichbed is intended to serve as a support for the blanks to be infolded insaid machine. In coperative relation with said bed is infoldingmechanism, and for convenience I have illust-rated a species of infolderoperating iechanism similar to the mechanism shown in an earlier Patent,No. 707,030, issued to me. Such mechanism consist-s, generally speaking,in a series of infolding members or infolclers suitably spaced aroundthe center of the bed of the machine according to the form of the blanksto be infolded. These infolders are represented in Figs. l to etinclusive by the character C, and they may be said to comprise inwardlyand outwardly movable members to t-he iimer ends of which the infoldersproper or infolding plates are secured; in cooperation with guiding`means, such as the slide-ways C, which are secured to the bed of themachine in a manner similar to my aforesaid patent. For operating saidinfolders or in other words for effecting their inward and outwardmovements, I have shown an operating mechanism similar to that of myaforesaid pat-ent, namely, one consisting in an oscillating part or ringfitted in a suitable slideway, annular in form in the particular eX-ample shown in the drawing to correspond with the circular form of theoscillating part or ring. This oscillating ring is provided with ahandle D for eecting its operative movements, and is further providedwith cams B which are preferably removable and adjustable in lsaid ring.The purpose of said cams is to afford a. cam connection between the ringand t-he inwardly and outwardly moving members which carry the infoldersproperly.

In the particular machine illustrated in the drawings and which, asbefore stated,

illustrates my invention as applied to a cuff having four squarecorners, I have indicated each of the infolders for the four sides ofthe blank as being formed in two halves, each half being separatelymovable sov that in effect there are eight infolders. F or convenience,however', the guiding mechanism for each pair of infolders is identical.One advantage of this being that I am enabled to employ the sameinfoldi-ng actua-ting ca-m for the two halves of each of said duplicateilnfolders.

Before describing the fold-defining and pressing mechanism, I willybriefly outline the operation of the particular infolders illustratedin the drawings: Assuming the blanks resting upon the bed to be definedby a suitable die or templet, t-he operator vby means of the handle Doscillates the infolder actuating ring with its cams B, the firstImovement `being in the direction of the hands of a watch, the Vfirstresult of such movement would be the engagement of the eccentric portionof the severa-l cams B with cam-pins connected to one of each of thefour pai-rs of Iinfolders so that alternate infolders around theperiphery -of the blank will receive an inward infolding movement. ThisIopera-tion will be followed by t-he continued r-movenient of the handleD by the engagement with the eccentric portions of said lcams B with thecam pins of the remain-ing` alter-nate infolders to Veffect their inwardmovement. The purposes of thus effecting the infolding of theblank-edges in successive infolding operations is the production ofblanks having what are known as lock-corners, which are -now well knownin the art. An advantage of the particular operation I have justdescribed is :the production of lock-cornered blanks, any two of whichwill interlock without the necessity of manufacturing blanks of twospecies capable of being fitted together.

rlhe above described species Aof infolding mechanism is a convenientone, especially for `the particular form of blank thereby intended to beinfolded; but I do not limit myself `to such species of mechanism butwish to cover the use of any known form of infolding `mechanism in whichthe number and contour of the infolding members will depend upon theform of the fold to be produced. l prefer, however, to employ mechanism-in which infolding plates or infolders are capable of 'to and fromovements from an outer or normal `position to an inward position within'the edges of the folded blanks.

I shall now describe a member lor part adapted to Vfill the office lof adie or templet for defining :the folds of blanks, and the further olliceof effecting a suitably powerful creasing pressure upon the folds of theblanks, and :preferably bythe squeezing operation between the infolderswhile in their inward position and the blank supporting portion or bedofthe machine.

From the above general description, it will be seen that there exists inthe machine of the present invention dual operative relations bet-weenthe infolding mechanism or instrumentality and the blank-defining andpressing part or member, which latter may properly be called thetemplet. These dual relations are the cooperation in the earlieroperation of the machine wherein the vtemvplot serves to define thefolds while the infolding mechanism serves to turn over the edges 'ofthe blanks defined by the templet; while in the later loperation of themachine after the templet has been withdrawn from the folded edges of'the' blanks, it serves to connmmicate Vto the infolding mechanism 'orinfolders a suit-ably powerful creasing pressure, while the foldingmechanism serves to retain the blank-edges undisturbed in their foldedposition, and to receive from ythe templet :and yto communicate to theblank-edges such creasing pressure. A great advantage will be at onceapparent from the arrangement 4permitting the creasing pressure to -beapplied to the folds of the blanks, while the infolders are in ytheirinward position, and before their disengagement with `the ifnfolds, forthe reason that an 'outward movement of the infolders previous to thecreasing and fixing ofthe folds would 'have a tendency to disturb andwould endanger the accuracy of the folds.

lVhile the temp-let of my invention may comprise any form of mechanismfor defining' folds of blanks during the operation of the infoldingmechanism, I -rhave in the specific machine illustrated herein shownsuch templet as comprising, together with an `edge portion or stock andactuating mechanism, a series of itempflet plates fitted to expand andcontract, or, in other words, to assume different positions relativelyto the ledge portion of the templet and relatively to the blanks to beinfolded. lith such species of templet,'there will be what I shall terma normal position, that is, a position in which :the plates of :theltemplet bear such correlation as to properly define or outline the formof the folded blank. Such templet should be further fitted andconstructed -so that its plates or the edge portions thereof, whichdefine the folds of the blanks, may be contracted or withdrawn from saidfolds after their formation, and this 'operation I shall term thecontraction of the templet.

To insure Vthe proper positioning of the templet upon the blanks restingupon the bed of the machine, it is usual to provide a templet supportingarm. I have illustrated such farm in drawings annexed hereto, and thesame is designated bythe letter H. On

the rear end of the arm H suitable pivoting mechanism, such as theadjustable pivots J may be provided for insuring an accurate upward anddownward swinging movement of the templet which is located at theforward end of the arm H. To the rear of the pivots J, I have shown achain K for suspending the counterbalance weight K from the rear end ofthe arm H.

Referring now more particularly to the Figs. l, 2 and to 9 inclusive,the templet will be seen located at the forward end of the arm H, andthe same comprises a body portion or stock E to which are fitted thetemplet plate guiding and operating mechanism. The templet plates arerepresented by the letters F, and in the form of templet shown hereinthe same consists of four diagonally moving plates. These plates arepreferably of such extreme thinness that a fold of appreciable sharpnessmay be formed over the edges thereof to insure the production of anaccurately folded blank. For efn fecting the inward and outwardmovements of the templet plates are provided slide-ways for guiding theplates in their movements, and cams cooperating therewith. G representsa forwardly extended handle fitted to oscillate about a pivot locatedupon the templet stock. The thin templet-plates F are secured beneaththe stronger and more solidly constructed parts F, which may formintermediate connections between the templet plates and their actuatingmechanism.

The use of cams and guideways for the purpose of operating infolderplates is not of itself new. Therefore, l will not describe in greatdetail the construction of my emplet. The diagonal slide-ways will beclearly seen in Figs. 6 and T. Fitted to each of the diagonal slide-waysis a roller f for making a cam engagement with two horizontal moving camplates G G, which in turn are connected by means of links g g to theoscillating member or handle G, whereby the operator may effectthehorizontal movements of the cam plates G G, and the diagonal inward andoutward movements of the templet plates F, by oscillating the handle G.Forward of the templet stock and connected rigidly to it is a memberwhich may conveniently be made in the form of a sector Q, and thepurpose of the sector Q is to provide shoulders or stops s s S2 .S3adapted to cooperate with the latch device R, secured to the oscillatinghandle D. Then the handle G is in such position that the latch R is incontact with the shoulder s of the stop or sector Q, the templet plateswill be in their inward or contracted position, as shown in dotted linesin Fig. G. @n the other hand,

when the latch R is in contact with the stop s near the other end of thesector Q, the templet plates will be in their normal positiem-that is,the position which they assume when the templet is of the size of thefolded blanks. The handle G will be in this position during the periodthat the templet is resting upon the blanks and while the blanks arebeing infolded.

ln addition to the shoulders or stops s, s of the sector Q, are providedadditional stops si' and s, which aire further removed from the stop sthan the stop s', and the purpose of the shoulders or stops s2 and s*will be explained hereinafter'.

Referring to Fig. l0, the stop R will be seen in enlarged detail view,and it is shown as consisting in a long arm which extends beneath thehandle G and may be grasped at the same time with the handle G, and ashort arm fr which is rigid with the arm R. The arm fr eo-acts with theshoulders or stops s, s', s2, s heretofore mentioned and is controlledby the operator through the long arm of the latch l. A springo7 isprovided to hold the latch in normal position with the arm i", incontact with the sector Q, or one of the stops thereof.

l will now describe how the die or templet employed according to myinvention, to effect the pressing of the folds of the blanks.

Referring now to Fig. 2, the templet plates are shown in their normalposition,-that is the position which they assume while the blank edgesare being infolded. Before the pressing of the edges of a blank it isadvanta geous to remove the templet plates in order that a sharper foldor crease may be produced. After the templet plates have been withdrawnfrom the folds of the blanks, or with the specific templet hereinillustrated contracted, the templet may be slightly elevated above thenormal position shown in According to my invention, the templet platesare then expanded to an extreme outward position, in which position theywill occupy an area of greater size than the normal area, and greaterthan the size of the blanks which have been infolded. rlhis additionaloutward movement of the templet plates is pro fide-d for in the machineillustrated in the drawings hereto annexed, by the provision of the stopalready mentioned, which is located at the exereme right end of thesector Q` (Fig. 6). Then the templetcontrolling handle G is moved by theoperator to the extreme position represented by the stop s3, the templetplates will be expanded to their extreme outward position, and thiscondition is shown in F 3. The templet may now be lowered to rest uponthe infolders, which are still in their inward poi sition havingeffected the inturning or infolding of the edges of the blank.

rlhe reason for effecting the additional outward movement of the templetplates just referred to, will be clear from the following llOexplanation, referring to Fig. 2. As already stated, the edge portionsof the templet plates themselves must, in order to do their workproperly, be comparatively thin and Substantially sharp on their outeredges. 1With this necessary construction it is manifest that the templetplates themselves would not have suliicient strength to connnunicate tothe infolders a pressure which would be capable of producing anycreasing effect in the folders of the blank. The additional outwardmovement given to the templet plates, as shown in Fig. 3, is sufficientto bring the heavier and stronger members F to which the thin templetplates are secured, in a position directly above the infolders. lf now,with the parts in the position shown in said Fig. 3, a powerful pressureis brought to bear upon the templet, such pressure will be communicatedby the templet to the infolders, and through the instrumentality of theinfolders will effect a proper creasing of the in-turned edges or foldsof the blanks, so as to fix them with a sharp crease or fold.

I will now describe a convenient mechanism for producing a suitablypowerful creas ing pressure as described. This mechanism is bestillustrated in Figs. l to 4 and may be described as consisting of afoot-lever or treadle O, having means intermediate of the treadle and ofthe templet or its positioning mechanism, whereby the operator uponpressing the treadl-e may bring to bear the weight of his body, whichwould be largely increased in proportion to the ratios of the severalmechanical elements intermediate the treadle and templet. A very heavypressure is required to be applied to the folds of the blanks in orderto give them sufficient sharpness and iixity of crease, and it has beenfound in practice, that a pressure of at least one ton is almost alwaysnecessary, when distributed over the area of an ordinary blank such asthat of a cuff. To produce such pressure in the machine of the presentinvention, I have shown a link P, pivoted to the treadle O at a pointnear its pivot 0, and at its up per end the link P is pivoted to theouter extremity of a second lever 0', which is pivoted to a fixed partof the frame.

Intermediate of the fixed pivot of the lever O and its outer extremity,is pivoted a pressure hook L, which is a convenient n'ieans ofdetachably connecting the treadle to the templet-positioning mechanism.The hook L is adapted to connect with a projection 71. that is rigidwith the templet-supporting arm H. lV hen the hook L is inengagement-'with the projection z, and the operator presses the treadleor foot lever O, it will be seen that the depression of the treadlecauses a depression of the templet-carrying arm and the templet.

An automatic means for `effecting the engagement of the hook L and theprojection la,

may be provided for convenience, and the following mechanism is thatwhich I have chosen to illustrate in this connection. 7b2 represents aroller that turns on a pin fast in the frame of the machine just to therear of the hook L, at a point above its pivotal connection with thelever O. Said roller h2 is adapted to co-actwith a cam formed upon thehook L. This cam takes the form of a slight curvature at /t which in thenormal position of the parts engages with the roller it?, as shown inFig. 2. A tension spring is extended between an eye provided on the hookL and the fixed part of the frame to the rear thereof, so as to afford atendency for the hook L to oscillate rear 'ardly, thereby holding thehook in contact with the roller 71,2 and out of engagement with theprojection le. on the templet-supporting arm H.

On depressing the treadle, the parts just described will operate asfollows: The link P will cause the lever O to oscillate downwardly, andthat in turn will cause the hook L to move downwardly. Immediately thisoccurs, a cam action takes place between the cam formed by the curvatureat it of the hook L and the roller h2; this cam action having the resultof throwing the hook L forwardly, whereby on a continued downwardmovement of the parts an engagement is effected between the hook L andthe proj ection z., so that the weight of the operator, increased in theratio due to the leverage described, will be brought to bear in adownward direction upon the templet, thereby forcing the infolders, asshown in Fig. 3, toward the bed of the machine, to effect a pressing ofthe folds of the blanks between the infolders and the bed.

A possible operation with the machine above described is illustrated inFig. t. For example, after the pressing has been effected as shown inFig. 3, the operator may, if he desires, move the infolders outwardlyand then apply the templet in its normal extending position, to thefolds of the blanks for a further pressing. This operation, however, isnot the preferred operation of the machine herein.

I will now give a general statement of the preferred operation ofmachine heretofore described. TWhen idle, the templet andtemplet-carrying arm may be elevated to an angle of about 4:50, thecounterbalance K retaining them in this position. The Operator willplace a blank of one or more thicknesses of fabric upon the bed of themachine, with its edges overlapping the infolders. The operator willthen position the die or templet upon the blanks, preferably for thatpurpose using the handle Gr, and the templet plates after the templet isin position upon the blanks, will be in what I have hereinbeforedescribed as their normal position,-that is, the position that they willoccupy when the rio handle G engages the stop s. The die or y templetwill i then correspond in size and form with the infolded blanks to beproduced. The next operation will be the rotary movement of the handle Dand its connected ring and cams to effect the inward or infoldingmovements of the infolders. This will effect the in-turning on infoldingof the edges of the blanks where they extend beyond the edges of thetemplet. The infolders will now be allowed to retain their inwardposition directly above the infolds of the blanks. The operator willthen contract the templet by throwing the handle G to the left, intoengagement with the stop S. The templet may then be elevated and will beexpanded according to my preferred operation, to the extreme limit ofits expansion represented by the stop S3, in which position th e heavierportions of the templet to which the thin plates are attached, will comedirectly aboviJ the infolders, and the templet will then be. allowed tocontact with or rest upon the infolders that are still in their inwardposition with the folds of the blanks beneath them. The next operationis the depressing of the treadle in order to communicate a suitablypowerful creasing pressure to the infolders through the die or templet,whereby the folds of the blanks are pressed and fixed with a sharpcrease.

As it is customary in the art that the bed of the machine may be heated,and I .have shown the bed made hollow for that purpose, the heating, ofcourse, may be accomplished by means of steam or gas and in itself formsno part of the present invention.

The outward movement of the templet plates beyond the normal position,together with the heavier and stronger parts of the templet to which thetemplet plates are connected, form an important feature of the presentinvention, in that they constitute a provision whereby a templet whichwould otherwise be incapable of effecting any adequate creasing pressuremay be employed as hereinbefore described. IVhon the templet is employedfor giving pressure directly to the blanks, without the interposition ofthe infolders, as shown in Fig. 4, it is desirable to accord the templeta slight degree of expansion beyond the normal, inasmuch as a foldedblank is slightly larger than the templet over which it is folded, andin such operation with the parts shown as in Fig. l, thetemplet-operating handle G will be in engagement with the stop s2specially provided for that purpose.

20. 1n a folding machine, a support for a blank to be folded, anexpansible templet, an infolder, means for moving said infolder inwardlyover the edge of said templet to fold an edge of the blank, means forwithlrawing said templet from its fold-defining position in a planeapproximately parallel with that of said support, means for expandingsaid templet beyond its fold-defining position to cover an edge of saidinfolder, and means for forcing said infolder toward said support toproduce a creasing pressure on the folds of the blank, said forcingmeans operating through said templet when so expanded.

21. 1n a folding machine, a blank support, an infolder, a fold-definingmember, means for lowering and raising said fold-dening member upon andfrom a blank to be folded, pressing mechanism, said pressing mechanismand said fold-defining member being disconnected during the foldingoperation, whereby the fold-defining member may be raised and loweredindependently of the pressing mechanism, and means for operativelyconnecting the pressing mechanism and the fold-defining member, wherebythe fold of the blank may be pressed through the agency of saidfold-defining member.

22. 1n a folding` machine, a blank support, an infolder, a fold-definingmember, means for lowering and raising said fold-defining member uponand from a blank to be folded, pressing mechanism, said pressingmechanism and said fold-defining member being disconnected during thefolding operation, whereby the fold-defining member may be raised andlowered independently of the pressing mechanism, and automaticallyengageable means for operatively connecting the pressing mechanism andthe fold-defining member, whereby the fold of the blank may be pressedthrough the agency of said fold-defining member.

23. In a folding machine, a blank support, a plurality of infolders, anexpansible folddefining member, means for lowering and raising saidfold-defining member upon and from a blank to be folded, pressingmechanism, said pressing mechanism and said folddefining mechanism beingdisconnected during the folding operation, whereby said fold-definingmember may be raised and lowered independently of said pressingmechanism, and means for operatively connecting said pressing mechanismand said fold-defining member, whereby the fold of Jche blank may bepressed through the agency of said fold-defining member.

Q11. ln a folding machine, a blank support, a plurality of infolders, anexpansible folddefining member, means for lowering and raising saidlold-deiining member upon and from a blank to be folded, pressingmechanism, said pressing mechanism and said folddefining mechanism beingdisconnected during the folding operation, whereby said folddefiningmember may be raised and lowered independent-ly of said pressingmechanism and automatically engageable means for operatively connectingsaid pressing mechanism and said fold-defining member, whereby the foldof Vthe blank may be pressed through the agency of said fold-deliningmember.

In btestimony whereof I have signed J[his specication in the presence oftwo subscribing witnesses.
